We were getting many compliments at the grocery and gas stations about our U.S. Flag Mask so we decided to put a limited supply up for sale with a U.S. Flag package deal. The National Flag Company is making a limited quantity of U.S. Flag masks using cotton material in their factory. We are not mass producing masks. The 3×5 ft. U.S. flag is made of 200 denier nylon with sewn stripes and embroidered stars. The mask is made of 2 layers of broadcloth cotton with elastic loops. One size fits most.
